This has been bugging me ever since I saw the latest Star Trek film...
I am willing to accept an obscure substance (red matter) that creates singularities. I am also willing to accept the possibility of a device that can bore to the core of a planet and then somehow keep the tunnel open.
What I cannot understand is why Nero needed to place the red matter in the core of the planet in the first place. Surely, if the created singularity is powerful enough to suppress the effects of a supernova, it should be able to destroy a planet even when placed on its surface. The drilling process seems to me like an unnecessary risk for the Narada.
Now, the drill platform gave a nice excuse for the Narada staying in the same place for some time, as well as for the space-drop scene and then for Sulu swinging around a sword, but I am sure they could have found another reason if they needed to. Is there a semi-official (i.e. in-film or from interviews/deleted scenes/whatever) reason for the use of the drill?
